studies undertaken during the last 5 years in the babol research station of the institute of public health research, teheran university, with the collaboration of the international agency for research on cancer in the caspian littoral and ardabil area in the north of iran has indicated the presence of cancer in 48 different sites. the five more prevalent types of cancer found in that area in or...
As there has been no previous information on the consequences of telomerase expression in genetically altered, mortal cells derived from pre-malignant tissue, we sought to determine the effect of hTERT (human catalytic subunit of telomerase reverse transcriptase) transduction of pre-malignant cell strains from Barrett's esophagus that do not contain telomerase activity and possess a finite life...
Complications after treating esophageal strictures with prostheses and stents – 20 years’ experience
INTRODUCTION Over 80% of patients with esophageal cancer are qualified only for palliative treatment. The main goal of the therapy is to eliminate symptoms of dysphagia. AIM To analyze complications after insertion of prostheses and stents in patients with inoperable cancer of the esophagus/cardia. MATERIAL AND METHODS From 1996 to 2015 prostheses of the esophagus were implanted in 1309 pat...
Incidence of esophageal adenocarcinoma (EAC) has increased sharply in Western Europe and United States over the past three decades. Nearly all cases of EAC in the west are thought to be associated with Barrett's esophagus (BE) at the time of diagnosis. Regions in the Henan province of China have one of world's highest incidences of esophageal cancer, yet recent temporal trends in the relative r...
Relevance: Barrett’s esophagus (BE) is a special disease characterized by metaplasia of the flat epithelium esophagus.
 The main danger esophageal epithelial high probability develop-ing malignant neoplasm at site the
 lesion – adenocarcinoma or can-cer cardioesophageal zone.

Right aortic arch is a rare congenital vascular anomaly, thus, the surgical resection of esophageal cancer in a patient with this anomaly is extremely uncommon. The surgical treatment of esophageal cancer was performed in a 73-year-old man with right aortic arch. An upper GI series and endoscopy revealed Type 2 esophageal cancer in the lower thoracic esophagus. Chest computed tomography reveale...
Adenocarcinomas of stomach and esophagus are frequently associated with preceding inflammatory alterations of the normal mucosa. Whereas intestinal metaplasia of the gastric mucosa is associated with higher risk of malignization, Barrett’s disease is a risk factor for adenocarcinoma of the esophagus. Barrett’s disease is characterized by the substitution of the squamous mucosa of the esophagus ...
Introduction: The functionality and quality of any treatment planning system (TPS) strongly depends on the type of Algorithm which is used by it. Obviously, the role of dose distribution algorithms in calculation of prescribed dose inside the tumor in modern radiotherapy techniques has more important than past to achieve the best clinical outcomes, especially in tumors which ar...
Barrett's esophagus is a condition in which the normal stratified squamous epithelium of the distal esophagus is replaced by intestinal metaplasia. For more than three decades, the prevailing clinical paradigm has been that Barrett's esophagus is a complication of symptomatic reflux disease that predisposes to esophageal adenocarcinoma. However, no clinical strategy for cancer prevention or ear...
The tetraspanin CD63 has been described to have critical roles in multiple biological processes, including tumorigenesis and metastasis in several types of cancer. However, its role in esophageal carcinoma (EC) has not been reported. In the current study, immunohistochemistry was used to investigate CD63 expression in 106 esophageal cancer samples, 49 adjacent esophagus tissues and 17 normal es...
